Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies) The work of preparing International Standards is normally carried out through ISO technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2

The main task of technical committees is to prepare International Standards Draft International Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights ISO shall not be held responsible for identifying any or all such patent rights

ISO 17510-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 3, Lung ventilators and related equipment

This second edition cancels and replaces the first edition (ISO 17510-1:2002) which has been technically revised

ISO 17510 consists of the following parts, under the general title Sleep apnoea breathing therapy:

⎯ Part 1: Sleep apnoea breathing therapy equipment

⎯ Part 2: Masks and application accessories

Trang 6

`,,```,,,,````-`-`,,`,,`,`,,` -Introduction

Sleep apnoea is the clinically significant intermittent absences of normal respiration occurring during sleep The awareness of the risks associated with sleep apnoea has grown significantly in recent years As a result, the use of sleep apnoea breathing therapy equipment has become common This document covers basic safety and essential performance requirements needed to protect patients in the use of this equipment

This document is a Particular Standard based on IEC 60601-1:1988, including Amendments 1 (1991) and 2 (1995), hereafter referred to as the General Standard The General Standard is the basic document for the safety of medical electrical equipment used by or under the supervision of qualified personnel in the general medical and patient environment It also contains certain requirements for reliable operation to ensure safety

The General Standard has associated Collateral Standards and Particular Standards The Collateral Standards include requirements for specific technologies and/or hazards and apply to all applicable equipment, such as medical electrical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc The Particular Standards apply to specific equipment types, such as medical electron accelerators, high frequency surgical equipment, hospital beds, etc

NOTE Definitions of Collateral Standard and Particular Standard can be found in IEC 60601-1:1988, 1.5 and A.2, respectively

To facilitate the use of this document, the following drafting conventions have been applied

This document uses the same main clause titles and numbering as the General Standard, for ease of referencing of the requirements The changes to the text of the General Standard, as supplemented by the Collateral Standards, are specified by the use of the following words

cross-⎯ “Replacement” means that the indicated clause or subclause of the General Standard is replaced completely by the text of this document

⎯ “Addition” means that the relevant text of this document is supplementary to the requirements of the General Standard

⎯ “Amendment” means that existing text of the General Standard is modified as indicated by the text of this document

To avoid confusion with any amendments to the General Standard itself, a particular numbering has been employed for elements added by this document: subclauses, tables and figures are numbered starting from 101; additional list items are lettered aa), bb), etc., and additional annexes are lettered AA, BB, etc

Throughout this document, text for which a rationale is provided in Annex AA is indicated by an asterisk (*)
